Just curious Adam, was there a reason you decided to manually correct the column defects, as opposed to the using the scripts LinearDefectDetection and LinearPatternSubtraction?
At the time I created this image, LDD/LPS was not optimized.
Hi Adam, I really appreciate your effort to walk us through the challenges an image can present and how you approach solving them, including alternative approaches. A tremendous learning experience. Thank you.
Hi Adam,
Thanks for the detailed tutorial. I prefer detailed tutorial myself. What a journey through the many problems in these pictures. Was very inspiring to see how other people solve this kind of problem. I hope to see more tutorials like this from you.
Greetings Willy
Very helpful and informative! :)
